| 摘要 |
<p>The invention relates to a device for creating vacuum in the exhaust system that is used for reducing the fuel consumption by accelerating the discharge of exhaust gases from the cylinders of internal combustion engines which fit out various locomotion means. According to the invention, the device comprises a pipe (1) which leads the flue gases to a diffuser (2) provided with perforations (a) shaped as the holes of a grater, whose downstream end is attached to a jacket (3) which rests upstream on the pipe (1) by means of some stiffening members (4), which is meant to collect the atmospheric air which passes through the perforations (a) into the diffuser (2) where, due to the suction effect, accelerates the flue gases towards an exhaust opening (5) provided with some convoluted concentric blades (6) which form some channels (b) ensuring a noiseless separation of the air-gas jet from the components of the exhaust opening (5).</p> |
